Hey guys, I live in a really old farm house with very thick rock walls. We currently have 2 routers on either side of the house. Internet1 and Internet2 (both use the same password). I was wondering if it were possible to combine them so that I didn't have to keep disconnecting from one and connecting to the other depending where I am in the house? I know its got to be more complicated than just using the same SSID name for both of them! Thanks!

You can make them switch at a lower level by adjusting a setting called roaming aggressiveness. Not all nics have this but many do. The risk you take is you set it too aggressive and it jumps back and forth. There will be small stalls when it does this because it must reauthenticate and regenerate the encryption keys. It is a trade off between low signal levels and stability.

Now if these are actual different ISP connection or even if these are just different subnets you have a major issue. What will happen is the wireless connection will switch over but the IP stack will never see the port go down so it will assume the ip is ok. If the ip are different...or even if you make them the same the macs will be different ...you have...
As ThatVietGuy said, it really is just as easy as making them both have the same SSID (make sure they are on different channels though). The problem is devices are very stubborn about letting go of a weak signal in favor of a better signal. Usually they hang on to a signal until it is totally unusable before they search for a new one. Once again as ThatVietGuy says, try using separate SSID's with the information saved on the device. The device should automatically attach to the SSID as you move around the farmhouse. If it does not change (because it is holding on to the weaker signal from the other AP) then it most likely will not automatically change to the stronger AP even if they do have the same SSID.
 


If you happen to have a wifi router or AP that allows you to change the output power that can help. I had a similar situation where my indoor AP was plenty strong for my house but would give poor performance in my back yard. I put in an outdoor AP but noticed that my devices hung on to the poor indoor signal. I ended up turning down my indoor signal until it was not seen outside, yet it is still plenty strong for inside my house. I also adjusted the power my outside AP put out. Now I have no problems when I go from outdoors to indoors and back.

It's just the standard FIOS router, do you know off hand if its possible to turn the signal down on that?

What will happen is the wireless connection will switch over but the IP stack will never see the port go down so it will assume the ip is ok. If the ip are different...or even if you make them the same the macs will be different ...you have massive issues. You generally have to manually release and reobtain a IP address. This also does not fix the problem that if you really have 2 internet connection now your external IP has changed. This mean all your open session will be closed. You are not going to get a transparent hand over in a environment like this with consumer equipment. Cisco site has lots of information on stuff like this under what they call ip mobility. It is very interesting read on how complex this problem is to really solve.
